Elliptical Galaxy With an Ignored Remote X-ray Source
The story is about an ultramassive black hole but it ignores a remote X-ray source.
The black hole at the center of this galaxy is part of a survey of 18 of the biggest black holes in the universe. This large elliptical galaxy is in the center of the galaxy cluster PKS 0745-19, which is located about 1.3 billion light years from Earth. X-ray data from NASA's Chandra X-ray Observatory are shown in purple and optical data from the Hubble Space Telescope are in yellow.
The main image has a layover graphic with labels which appears with a mouse-over.
There are tabs for different wavelengths.
The X-ray image shows two sources at the core, one over the other. This could be the plasmoid (like in M87) observed perpendicular to the torus axis.
In radio the pair is resolved as an intense 'ball' within a 'T' structure.
Perpendicular to this pair and far to the right in optical is a 'blob' but inactive in radio or X-ray. This blob could be the remnants of a jet considering this alignment.
Alternating clicks on X-ray and optical reveals there is an object in both wavelengths in the 4 o'clock direction from the core.
However the entire right half of the radio image is blank; it has only the core in the middle.
The M87 plasmoid was observed in both X-ray and radio. One cannot know if the radio image had a reduced field of view but that is likely when the narrow focus of the study is on the black hole.
The lack of an object in radio prevents confirmation of a connection.
Usually an X-ray point source is considered a black hole but this story ignored this black hole candidate.
If this remote X-ray object is not a plasmoid then this star is quite the coincidence to be exactly in line with an X-ray point source having an intensity similar to emissions near the galactic core.
There are X-ray point sources found at some distance from a galaxy, perhaps an ejection. I have posted about several cases and this is another. Intergalactic space is not limited to just its medium but there are electrically active objects out there.
